Influence of interspecific hybridization on fitness-related traits in Siberian sturgeon and Russian sturgeon [PDF]
Czech Journal of Animal Science, 2019 Polyploidy in sturgeons makes them highly susceptible to interspecific hybridization, and these interspecific hybrids have been described in nature as well as in captivity. Nevertheless, the fitness-related traits between sturgeon hybrids and pure species have been poorly compared as yet.

Physical characteristics and simulated transport of pallid sturgeon and shovelnose sturgeon eggs [PDF]
Journal of Freshwater Ecology, 2020 The imperiled pallid sturgeon (Scaphirhynchus albus) and closely related, but more common, shovelnose sturgeon (S. platorynchus) are believed to broadcast adhesive, demersal eggs in the current and over coarse substrate in turbid rivers of the North American midcontinent.

Characterization of AHR1 and its functional activity in Atlantic sturgeon and shortnose sturgeon [PDF]
Aquatic Toxicology, 2018 Sturgeon species are imperiled world-wide by a variety of anthropogenic stressors including chemical contaminants. Atlantic sturgeon, Acipenser oxyrinchus, and shortnose sturgeon, Acipenser brevirostrum, are largely sympatric acipenserids whose young life-stages are often exposed to high levels of benthic-borne PCBs and PCDD/Fs in large estuaries along
